This'ainve'ntion relatesto aacombinationpresser foot and gauge forsewin'g, machines, hem, .seam or li-lreapparatus.

'Inwpractice it has been foun'd' desirable, inparticular-whenusingrknown'capm'achines, 'to re- 7 duce'thenumber of sewing; operationson the band "materialto be applied'to the cape! hat body,,to'which bandmaterial lining and size strip are to be joined.

Inorder'to reduce these sewing operations and manipulations of' the workpiece to a minimum, the present invention-proposes certainimprovementsin presser foot structures; It is, therefore, oneof theprimary objeotsof this inventi'on" to'provid-e'm'eans greatlyfacilitating adjustment; guidance and z'rdaptability of "the presserfoot to the 'shape-and'dimensions (width) of the workpiece which isto'b'estitched or sewn. It-is another object of the present invention toprovide means afiording 'simple construction and Yet, another object ofthe present invention" is-to'provide means permittin 'pivotal movementofsaid gauge so as-to employ the same also as an additional or auxiliarypresser foot piece, which'is kept under spring action.

Still a furtherobject of this invention is to provide means ensuingstraightening out and retaining the workpiece in substantially flatcondition Without regard to its thickness or serving as a' g'uide 'forone of the-edges ofsaid work piece. 40 With the above and other objectsin view, theinvention will be hereinafter more particularly describedand the' combination and arrangement of parts willbe shown in theaccompanying drawings and pointed out in the claims which 45 form partof the specification.

Reference willnow be had to the drawings 'wherein' like numerals ofreference designate corresponding parts throughout the several views,infwhich: I

Referring nowmore particularly to the drawings; Figs. 2 to 6illustrate acombination presser foot and gauge device I0 made in accordance withthis invention. The gauge device includes a pivotally supported guidelever or auxiliary presser foot II and an extension or slide member I2.

Extension member I2 is arranged for sliding movement and extends on theupper surface I3 0 of the mai-npresserfoot M. The main presser foot isprovided with a slot I 5 through which the needle Ifimoves for thesewing operation and has furtheran open slot II extending from the uppersurfacelitoth'e bottom surface I8 of the main presser foot -portioniSlotI'I terminates in an end wall I'Ia. Lever I I is adapted formovement within slot I'I andnormally projects below the-surfaceIBofpresserfoot I4, as illustrated in dot-dashlines inFig. 4. Lever IIcarries a pin 0 I9 on which is removably and interchangeably disposed aspiral spring 20 which extends for abutment against an arm 2I. This arm2| is perforated-at 2.2 topermit said pin I9 to project beyondar'm 2|.Lever orauxiliary presser foot Sdmember II is provided with the forwardportion I Iwwithroundedend, with areduced rearward portion-Ho whichterminates into a tongueshaped .portionllc. -Port'ion- IIb terminates inendlwall lie for contact and cooperation with endwall I'Ia.of.slot-l1..Portion He is adapted toirestonandengage the upper surface of extensionmemben-H; as seen in Figs. 2-and 5.

. It can thus be seen that forward portion I Ia of lever can either beswung upwardly about tongue-shaped portionJ Ic against the tension ofspring. (which maybe regulated in any known manner), or the forwardportion IIa oflever it together with its portions Ilb, He can be pressedupwardly (while end wall He engages slot end wall IIa) against theaction of said spring 20 to a position in which the lower edge 'I If issubstantially in alignment with the straight bottom surface I8' of mainpresser foot portion III (Fig.4)

Fig. Zis'a top pla view of thetpresser foot'and .65 Inthe'presentinst'ance, presser foot I is provided with r. projectingportion or nose 23 which is U-shaped in cross-section and forms alateral guide for the extension member l2, which is further guided byits engagement with a set screw 25 along slot 24.

Presser foot I4 has further an upwardly projecting guide portion 26which is bent at 28 and carries a screw bolt 21 for attaching arm 2| toportion 25. Portion 26 of the presser foot extends above the latter andis so curved at 28 as to form an additional lateral guide for theforward edge or end 29 of extension member l2. Extension member I2 isfurther provided with a downwardly extending abutment flange or rim 30which in retracted position of member l2 comes to lie flush with thebottom surface I8 It follows from the above disclosure, that accordingto this invention, there has been achieved a presser foot structureprovided with a connection for the foot bar of a sewing machine, whichstructure consists of a main foot member with a substantially flatbottom surface, which has a lateral edge and also a slot directedsubstantially parallel to said lateral edge. The presser foot structureis further equipped with an auxiliary member accommodated for movementin the aforesaid slot and provided with a guide edge adapted to extendbeyond said bottom surface of the main foot member; a

of presser foot |4 (indicated in dot-and-dash lines) In order to slideextension member l2 relatively to presser foot l4, all that is to bedone is to loosen set screw and then to slide member l2 along guides 23and 26 so that rim 30 extends beyond the lateral end 3| of presser footI4.

Rim 3!] of member i2 is thus guided parallel to edge 3|, while the wallsof slot 24 engage the stem 25a of set screw 25. Projecting portion 32 ofslide member l2 will move underneath the lower surface of tongue-shapedportion lie of lever ll without interfering with of the spring supportedlever l.

Presser foot I4 is further provided withan upwardly extending portion 33equipped with a slot 34 for the engagement of a screw 35 pro- 7 theposition vided on foot bar 36 of the sewing machine 31,.

(Fig. 1) whereby the presser foot and gauge de-' of the sewing operationduring which the flat base surface |8 of the presser foot l4 retains thefolded over portion 44 of the work piece 40 in position, while needle l6carryingthe thread (not shown) moves through the closed presser footslot I5. 7

If it is desired during further sewing operations, as it is often thecase in cap machines, to attach or sitch size band and lining cover tothe material of the hat body, work piece 40 may be guided along anauxiliary guide bar of a well-known auxiliary gauge .(indicated indotted lines). Upon adjustment of auxiliary gauge itby means of slot 41and set screw 48, as may be easily realized; slidable extension memberl2 with its upwardly curved forward part |2a may be spaced from thelateral edge 3| of presser foot l4 and its curved forward part Ma andmoved to a position in which flange 3D enlarges the bottom surface l8 ofthe presser foot and abuts against bar 45, thereby effectuatingandaiding in the retention of the projecting work piece portion onplatform 4| which work piece is guided alon bar 45.

.In such sewing operation, auxiliary presser foot member I I will recedeto a position as shown in full lines in Fig. 4., in which said memberpermits transport of the work piece on the platform while-said member llrides with relatively slight pressure on the work piece 40.

spring element is arranged to engage one end of said. auxiliary memberfor maintaining the latter in downwardly projecting position. therattached to the presser foot structure is an extension member located ontop of said main member and slidable thereon, said extension memberincluding a flange adapted in one extreme position of said slidableextension member to lie adjacent said lateral edge and substantiallyflush with the bottom surface of said main member. This flange is spacedin another extreme position of said slidable extension member from saidlateral edge and enlarges the bottom surface of said main member. Theauxiliary member includes also a tongue-shaped end piece which lies onthe top of said main member whereby said auxiliary member may be movedagainst the action of said spring element about said tongue-shaped endpiecewithin said slot so as to cause said auxiliary member to assume areceding position in which said guide edge will be located substantiallyflush with said bottom surface of said main member to thereby obtain asubstantially uninterrupted flat bottom surface.

It is further to 'be observed that the spring 20 may be easily adjustedas to its tension by any known means or may be readily replaced byanother spring exerting an appropriate pressure on said auxiliarypresser foot for application to the fabric or material to be workedupon.

In accordance with the above, it is well understood that deviations andchanges may be made from the embodiment herein set forth withoutdeparting from the spirit of this invention.
